nYNAmo SUSPENSION.

To all whom it may concern:

Be it known that I, WILLLAM F. Become, a citizen of the United States, and a madent of Depew, county of Erie, and State of New York, have invented certain new and useful Improvements in Dynamo Suspensions, of which the following is a speclfication.

- My invention relates to improvements in dynamo suspensions and more partlcularly to apparatus for supporting dynamos on car trucks, which dynamos are adapted to be driven from the car axle. One object of my invention is to provide a simple and efiicient arrangement, whereby the dynamo may not only be easily adjusted to tighten the driving belt thereof, but which arrangement shall also have but few parts, which are simple and easy of construction and assemblv. Further objects, features and advantages will more clearly appear from the "detailed description given below, taken in connection with the accompanying drawings, which form a part of this specification.

In the drawings Figure 1 is a plan view of one embodiment of my invention applied to a car truck. Fi 2 is a section taken on the line 22 of Flg. 1. Fig. 3 is a front view of the'same. Fig. 4 is a side view of the same. Fig. 5 is a detailed section taken on the line 55 of Fig. 4, illustrating the method of connecting two parts of the supporting frame.

In the drawings 1 represents the car truck, 2 one of the car axles and 3 the wheels thereof. Secured to the sides of the truck 1 are horizontal bars 4, one on each side of the truck, which bars project horizontallyv from the truck, passing through apertures in the end of the truck frame. 5, 5 represent additional supporting bars, having their outer ends bolted to the bars 4 at 6, and having, their ends bolted to the truck frame at 7. For a portion of their length, adjacent their outer ends, the bars 4 and 5 of each pair run parallel to one another and on top of these parallel portlons are placed supporting blocks 8. Each block 8 rests upon both the bars 4 and 5, and 1s apertured in its center as at 9, and provided with upwardly extending ears 10 and downwardly extending ears 11, lying adjacent to the bars Specification of Letters Patent.

4 and 5. The ears 11 are bolted to the bars 4 and 5 by means of bolts 12, which bolts pass through slots 13 in bars 4 and 5, in

order that blocks 8 may be adjusted for a short distance longitudinally on top of the bars 4 and 5, and secured in any desired adjusted position by means of the bolts 12.

Pivotally mounted between the ears 10, by

nected by a cross member 17 at theirlower 5 ends. The members 15, 16, 17 are preferably made of one integral rod, having an eye at the top through which the pivot 14 passes, in which member the portions 15, 16

may be considered asside arms and portion 7 17 as a cross piece connecting the lower ends of said arms, the lower portion of said member being bent backward to one side at.v thejunction of parts 15 and 16. Also near the lower end of the members 15, at the 7 junctionof the portions 15 and 16, there are provided laterally extending members or side arms 18, each clamped to one of the rods 15, where it is bent laterally adjacent its lower portion. The members 18 are clamped to the members 15 and 16, by means of clamping-plates- 19 and bolts 20 '(see Figs. 4 and 5).

' Connecting .the lower ends of the members 18 is a cross member 21. The members 18 and 21 are preferably made of one integral rod. The members or cross bars 17 and 21 are spaced apart and arranged substantially parallel to the car axle and spanned by members 22, clamped to the cross pieces 18 and 21 by means of cap plates 23 and bolts 24. The members 22' are provided with upwardly extending lugs 25, through which pass rods 26, and a dynamo 27 is provided with depending lugs 28 (see Fig. 3), through which the rods 26 pass, whereby the dynamo is rigidly supported upon the members 22, and consequently by the cross rods or bars 17 and 21.

Bars 4 at their outer ends are bent down- .pulley in the downwardly extending portion of spring 33 and tending to pull the-members 15 and the dynamo supporting frame out- 'wardly and away from the car axle about the pivots 14 as a center, to apply or increase the tension upon the belt 35, passing over a ulley 36 on the car axle and a on the dynamo, for the purpose of driving the dynamo from the car axle.

It will be seen that the arrangement for suspending the dynamo by a swinging structure is extremely simple, requiring but few parts, and yet the dynamo may be adjusted laterally along the bars 17 and 21, by loosening the clamping plates 23, and likewise a proper tension may be applied to the belt by operating the nuts 34 to swing the dynamo in or out, as desired. A slight adjustment may also be had of the supporting blocks 8, by means of the slots 13. Although I have described my invention with respect to its preferred form, nevertheless, li do not desire tobe limited to the embodiment shown and described, as many changes and modifications may be made without departing from the spirit and scope of my invention in its broader aspect.

What I claim as new and desire to secure by Letters Patent of the United States is:

1. A dynamo suspensiolf havin in combination with a car truck, supportlng members extending from the truck, a pair of blocks carried upon said supporting mem: bers, one at each side of the suspension, a supporting frame pivotally suspended from said blocks, said frame having two parts extending downwardly from said blocks respectively, two parts extending laterally from each of said-downwardly extending parts, one of said lateral parts being integral.

with said downwardly extending parts, and two spaced apart cross members parallel with the car axle, connecting the laterally extending members on one side with the laterally extending members on the other side of the suspension, and means whereby the dynamo is adjilstably carried by said I cross members.

2. A dynamo suspension havin in combination with a car truck, two pans ofbars extending from the truck, one pair on each side of the truck, the bars of each pair being spaced from and running parallel to one another adjacent the outer ends thereof, a pair of blocks carried upon said bars, one on each side of the truck, each block being bolted to each member of each pair of said bars, the bolts passing through slots in the bars, whereby adjustment of the blocks longitudinally'of the bars is permitted, and a .side of the truck, a pair of blocks carried igeaere swinging dynamo supporting frame pivotally supported from said blocks.
